Visual modeling and the Web Conceptual browsing with Conzilla Mikael Nilsson Royal Institute of Technology, Stockholm Conzilla An ontology-based browser
Contents Presentation of the institution. Conceptual browsing. Conzilla. Conclusions. How can ontology enhance the Web experience?
CID Center for user-oriented Information technology Design Academia industry and user organizations. Computer science, art, design, and more. Interactive Learning Environments How do we create/present modular, portable learning material?
Conceptual topologies Static topologies Content not reusable. Well-defined context. Example: textbook. Dynamic topologies Content reusable. Contextual anarchy. Example: hypertext “In what context am I viewing this?” How do we create reusable content without losing contextual clarity when browsing it?
Conceptual browsing Context content separated. Surf the context instead of the content. Concept-maps are (ontological) context. Concepts linked to content.
Conzilla Typed concepts/relations in XML—CORBA —... Can express ontological systems such as OIL (probably). Distributed design à la Web. Path URNs as identifiers. (urn:path:/se/sih/…) IMS/IEEE Learning Object Metadata (LOM). Usability and design.
Conzilla in action Web- browser Future: embedding and interaction Content Links to other maps Meta-data
Applications Conceptual Explorer –Mathemagics project at CID. Visual browser for –RDF(S)-based systems (OIL, etc.). –Notion, Topic Maps etc. –Meta Object Facility (UML models). Mobile ontology explorer. Etc...
Conclusions The Web badly needs semantics. Object modeling à la RDF(S) is a well-proven technique for conceptual organization. The advantages of both are combined in a conceptual browser. We are looking for cooperation possibilities. Interested?
